Hi, why does my stool smell sour? I thought it could be cause of acidity in stomach, but I have tried everything to alkaline and still smells sour :/

Not a disease. The "sour" smell of the stool is not a disease. Do not worry about it. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine.
